SubC Camera Comparison Guide

Researching, comparing, and choosing the right underwater imaging subsea camera for your project can feel like a monumental task. You might need a subsea camera for marine research. Or, you might be looking for a camera that can mount on an ROV for an offshore energy application. 

Whatever your need, our team will work with you to fully understand your situation so we can provide the best recommendation. While it’s always best to speak with a member of our team, today we’ve put together a head-to-head comparison of SubC’s cameras to help you understand your options and inform your choice.

SubC Imaging's Rayfin Coastal Camera

Rayfin Coastal 500m

Rayfin Micro 500m

 

SubC’s Underwater Cameras

The Rayfin Benthic is rated to 6000m deep, is constructed of Grade 5 Titanium, has the most live video feed options, and comes with up to four aux ports.This model is available with options for live 4K, HD, and IP video formats and is fully compatible with ROV, AUV, tow/drop, autonomous, and observatory systems.

Highlights:

Depth rating: 6000m

Application(s):  Live inspections and surveys; battery-powered systems, observatory/cabled array, and more.

Data Storage and Download: For battery-powered setups, the Rayfin Benthic offers an internal storage capacity of up to 40 hours in HD and 10.5 hours in 4K, allowing for post-inspection data download. For live inspections and surveys, the Rayfin Single Channel Inspection option provides instant media access and topside storage.

Data Logging: NMEA 0183 & 2000 format @ 10Hz

Autonomy & Timelapse: Available autonomous scripting and long-term hibernation timelapse with open-source API

Aux Ports: Two aux ports, capable of powering and controlling LED Strobe/Lamps, Lasers, and other devices. Up to four aux ports are available on Observatory models.

Rayfin Rapid Digital Imaging: Configurable, 2Hz (2 per second) to 0.1Hz (1 every 10 seconds)

Compatible SubC Imaging Systems: Autonomous, Observatory, Rayfin Single Channel Inspection, Rayfin 4K and HD Video Survey

 

The Rayfin Coastal is rated to 500m, constructed of anodized aluminum, and uses SubC Boost-Power Comms (BPC). BPC technology transmits power and data over a low-cost twisted-pair or coax subsea cable. It provides enough power to drive the camera, two LEDs, lasers, and other sensors while enabling live HD video and data to the surface. This can be used in drop/tow camera systems and for ROV 4K and HD upgrades.

Highlights:

Depth rating: 500m

Application(s):  Live inspections and surveys 

Data Storage and Download: For battery-powered setups, the Rayfin Coastal offers internal storage capacity of up to 40 hours in HD and 10.5 hours in 4K, allowing for post-inspection data download. Alternatively, for live inspections and surveys, the Rayfin Single Channel Inspection option provides instant media access and topside storage

Data Logging: NMEA 0183 & 2000 format @ 10Hz

Autonomy & Timelapse: Available autonomous scripting via open API

Aux Ports: Two ports, capable of powering and controlling LED strobe/lamps, lasers and other devices

Rayfin Rapid Digital Imaging: Configurable, 2Hz (2 per second) to 0.1Hz (1 every 10 seconds)

Compatible SubC Imaging Systems: Tow Camera System, Rayfin Single-Channel Inspection

 

The Rayfin Micro 500m ROV Camera is a lightweight and compact solution tailored for observation class ROVs. With its high-resolution imaging capabilities and real-time topside media transfer, it offers precise inspections and surveys. Engineered for durability, it seamlessly integrates into your system, providing clear visuals and data annotation, even in low-visibility conditions. Featuring Rayfin Rapid Digital Imaging (RDI), it ensures sharp image capture and instant storage topside, streamlining workflow efficiency during underwater operations.

Highlights

Depth rating: 500m

Application(s):  Live inspections and surveys 

Data Storage and Download: Uses Rayfin Single Channel Inspection software for instant media access and topside storage

Data Logging: NMEA 0183 & 2000 format @ 10Hz

Autonomy: Not available.

Aux Ports: Two ports, capable of powering and controlling LED Strobe/Lamps, Lasers and other devices

LiquidOptics Lenses

All Rayfin subsea cameras come with high-quality optics with our water-corrected LiquidOpticsTM. LiquidOpticsTM allows for advanced 1:1 water-corrected sapphire optic, enabling quality that is even higher than normal. It produces outstanding colour accuracy by minimizing chromatic aberration. It also increases the field of view and image sharpness while reducing distortion.

Compared to a generic flat port lens, SubC’s LiquidOptics™ provides sharper images with less distortion.
